摘要

Subterranean predatory mites are important biological control agents of pests in soil.In order to understand the population characteristics of two predatory mites,Macrocheles glaber Mller and Stratiolaelaps scimitus Womersley,we studied their development,survival and fecundity data under laboratory conditions using Coboldiafuscipes Meigen as a food source and analyzed them with the age-stage,two-sex life table.Macrocheles glaber had a significantly shorter developmental time,oviposition period,longevity and lower fecundity than those of S.scimitus.The intrinsic rate of increase (r),finite rate of increase (λ),net reproductive rate (R0),net predation rate (C0),and finite predation rate (ω) of M.glaber were significantly lower than those of S.scimitus.Both population parameters and computer simulation implied that S.scimitus is a potential powerful biocontrol agent compared to M.glaber.
